I quite enjoy watching some of their videos, and there have been a few occasions that left me wondering if a caution had been missed whilst the camera was off or somthing.
I'm certainly not the greatest ref in the world (as my last game showed), but I like to think that I'd have dished out more than one yellow if similar things happened in one of my games (I think my ref sec is going easy on me as a newbie, because the worst thing I've had is some mild dissent).
I think that if the ref had dealt with the first foul on the orange player then maybe the rest of it wouldn't have been necesarry, his inaction seems to have given the players the impression that anything goes.
However, that being said, it's easy for us to sit here and critise the ref after the fact.
